I bought several of these so I don't have to change paper in between. The good thing is that you can see through them as they rotate. But when sharpening wider chisels, I quickly find that they either bend or just aren't as flat. Marking the bevel with a marker showed that some areas were almost unpolished. This made the process very, very slow, and the result was that the edge was not perpendicular to the handle, even after making changes to the sharpening hole. When I switched back to the glass wheel, the grind was fast enough that I didn't mind. I can't see it and the edge is nice and square. I think these edge sight circles are a gimmick and only good if the tool needs a lot of roughing on 120 grit paper.
